First Measles Case of 2025 Reported in South Carolina

In an important development, a resident of Upstate South Carolina has been diagnosed with measles. The South Carolina Department of Public Health confirmed the case on July 9, marking the first instance of the disease in the state since September 2024. The infected individual is known to be unvaccinated and contracted the virus during an international trip. Currently, they are in home isolation and were not contagious during travel. Public health officials have begun contact tracing by notifying individuals who may have been exposed, and those contacts have voluntarily quarantined to prevent further spread.

Historically, South Carolina experienced significant outbreaks before the widespread availability of the measles vaccine, with nearly 6,000 cases reported in 1957 and only isolated cases since then. The recent case underscores ongoing concerns about vaccine coverage and herd immunity, especially since the individual was not vaccinated.

Expert opinions highlight the highly contagious nature of measles, which spreads rapidly through respiratory droplets and can remain infectious in the environment for up to six hours. Authorities emphasize the importance of vaccination, noting that the best way to prevent infection is through immunization. State epidemiologist Dr. Linda Bell urged residents to review their vaccination status and consult healthcare providers about the benefits of the MMR vaccine.

The return of measles presents a significant public health challenge. As of July 1, 2025, the CDC reported 1,267 confirmed cases across 35 states, including neighboring states Georgia and North Carolina. The CDC also identified 27 outbreaks in 2025, with most cases linked to these outbreaks. Texas has experienced a notable outbreak, with over 750 confirmed cases primarily among children and school-aged individuals, two of whom have died. The resurgence of measles reflects a broader trend of increasing cases in the United States, largely due to gaps in vaccination coverage.

Health experts have voiced concern over declining vaccination rates in South Carolina, which have fallen below the 95% threshold necessary for herd immunity. Such gaps can lead to outbreaks, especially in communities where vaccine refusal is culturally or socially motivated. Measles symptoms typically include a rash lasting several days, high fever, cough, and cold-like symptoms. Severe complications can include pneumonia and encephalitis, with a small percentage of cases resulting in death.

In response, health officials continue to stress the importance of measles vaccination for all age groups. Adults with healthy immune systems are encouraged to ensure their immunizations are up to date. The MMR vaccine is widely available at pharmacies and clinics, offering lifelong immunity when administered properly.

This case serves as a reminder of the ongoing need for vaccination and vigilance to prevent future outbreaks. Public health campaigns and increased awareness are critical in safeguarding communities from this preventable disease.
